The relation between intelligence and neuroticism was investigated considering six groups of subjects. These groups varied with respect to sex, socio-economic status and delinquency. A. Non-language test of Verbal Intelligence was used to assess the level of intelligence and an inventory modelled after Bernreuter's Personality Inventory was applied to measure the degree of neuroticism. The result shows that:
(a) The relation between neuroticism and intelligence was not just linear and in some groups higher order regression equation was found to be more suitable though the magnitude of the corresponding correlation ratio was not high.
(b) The nature of the observed relation between intelligence and neuroticism was not similar in all the groups considered here. In some cases it was positive whereas in some other negative relation was established.
